There are several ways to remove scale from boilers, and each method has its advantages and scope of application. Here are some common boiler scale removal methods and their advantages and disadvantages::
Boiler descaler.
Mechanical descaling method: The scale is removed from the inner wall of the boiler by means of mechanical tools such as high-pressure water guns or scrapers. This method is simple and easy, but it can damage the boiler wall and does not completely remove limescale.
Chemical descaling: The use of chemicals to chemically react with limescale to dissolve or decompose. Commonly used chemicals include acids, alkalis, salts, etc. This method can completely remove scale, but it requires strict control of the concentration and duration of the agent to avoid corrosion to the boiler.
Physical descaling method: through high-voltage electric field, ultrasonic and other physical means, the scale is physically changed and falls off. This method does not cause corrosion to the boiler, but may require high equipment investment and maintenance costs.
To sum up, the choice of which scale removal method needs to be comprehensively considered according to the specific situation of the boiler, the type and thickness of the scale, and other factors. It is recommended to consult a professional boiler maintenance personnel or manufacturer when choosing a scale removal method to ensure safety and effectiveness.
